Version 1.1.0 update: fixed numerous bugs and errors involved
HyperNumber is a high-precision large number system capable of handling numbers up to 10^^(1e50) and beyond with customization. It uses BigInt to handle such features, which is a feature that is now supported by all major browsers (well, except Internet Explorer, but does that really count?).
Within each instance of Hyper, there is a property, $. This property contains the data of the number, in which there is an array that looks like this with four values: [sign (1 or -1), category (non-negative number below the maximum safe integer or BigInt otherwise), digitsOfData, data]
Create a new instance using Hyper(string | number | bigint | Hyper) or new Hyper(string | number | bigint | Hyper). Read the source code for documentation!
Try out formatting and see how the array works HERE. (You can set the precision to any integer from 16 to 10,000,000 when actually using the algorithm.)
